Pilgrim's Bounty also plays host to a series of daily cooking quests designed to help chefs master their craft with seasonal recipes plucked from a Bountiful Cookbook. These quests require players to travel between the major cities of Azeroth and to fill the stomachs of armies with seasonal food. The reward for these quests is a Turkey Caller, a prize that ensures that the accomplished pilgrim will never go hungry again.

If you use it in Tirisfal Glades it will pull the nearest turkey( assuming it is one nearby) to you giving it a heart above like on Valentines event.

When used a Lonely Turkey will spawn nearby which will run towards you with a heart over its head, after a short while the heart will break and it wanders off. If you kill it you will be able to loot a Wild Turkey from it.
